jupyter No module named 'torch'

The error message "No module named 'torch'" suggests that the PyTorch library is not installed in your Jupyter environment. To resolve this issue, you need to install PyTorch in the same environment where Jupyter is running. You can do this by following these steps:

1. Open a terminal or command prompt.
2. Activate your desired Python environment (if applicable).
3. Run the following command to install PyTorch:

   pip install torch

Note: If you want to install a specific version of PyTorch, you can specify it in the command. For example: `pip install torch==1.6.0`.
4. Wait for the installation to finish.
5. Once PyTorch is installed, restart your Jupyter notebook and try importing the `torch` module again.

If you're using Anaconda, you can also try installing PyTorch using the `conda` package manager by running the following command:

conda install pytorch torchvision torchaudio -c pytorch

Make sure to activate your desired Python environment before running the command.

I hope this helps! Let me know if you have any further questions.
